Given only one side and two angles, the law of sines is the appropriate choice. To use that, you need to know the angles opposite the side of interest and the given side.
∠C = 180° - ∠A - ∠B
∠C = 180° - 35° - 65° = 80°
Now, the law of sines tells you
b/sin(B) = c/sin(C)
b = c·sin(B)/sin(C) . . . . . multiply by sin(B)
b = 15·sin(65°)/sin(80°)
b ≈ 13.8_____
Or you can use a triangle solver.
Is this multiple problems..?
Answer:
Option (B).
Step-by-step explanation:
Option (A).
A, F and B are lying on a line on the plane M.
True.
Option (B).
CD lies on the plane M, but its not clear that angle between the plane M and P is 90°.
False.
Option (C).
A, B and C are coplanar.
Since, these three points lie on the plane M, they are coplanar.
True.
Option (D).
Plane M intersects plane P in FH.
Since, line of intersection of the two planes M and P will be FH.
True.
Therefore, Option (B) will be the correct option.
Answer:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5

A 3x3 matrix has a characteristic polynomial of degree 3. If all the elements of the matrix are real, then the polynomial has up to 3 distinct complex roots. If one of these roots is complex (in particular, has a non-zero imaginary part), then a second root would be that first root's complex conjugate. Then the remaining root has to be real.
